Mice in the garage? Roaches by the sink? This is the one that covers the pest you have and the next one that shows up.

One pest, then another, then another?
The same plug-in covers them all.

Pests don't pick dirty homes. They pick reachable ones. Getting ahead of it isn't overreacting. One PestRx plug-in per room makes your home the harder target for rodents, roaches, spiders, and ants. The ones inside head out. The next ones settle somewhere else. No poison, no sprays, no traps near your kids or pets. Backed by our 30-day money-back guarantee.

Safe around kids & pets
30-day money-back guarantee
Made for homes with kids and pets.
Based on the layout of the room, a good rule of thumb is one device covers one room, but not all rooms require a device.
The most common complaint we hear comes from buying too few devices and undercovering the home. Not sure how many you need? Get your exact count in 2 minutes ↓

Why it's never just one pest

One pest is never just one.

One sighting is rarely the only kind you'll deal with. Rodents, roaches, spiders, and ants all work the same way: if your home is reachable, more follow. Handling them one product at a time is why the cabinet fills up and the problem never does.

  • Every pest is a different product Each pest gets its own spray, bait, or trap. The under-sink shelf fills with half-used products, and none of them keep the next kind out.
  • One device replaces the whole shelf Buying a separate spray, bait, and trap for each pest adds up fast, and most leave chemical residue along the baseboards your kids and pets touch. PestRx is one plug-in that covers all four.

What the one-at-a-time approach really costs

30,000
Roach offspring from one female in a year German roaches breed faster than almost any household pest, nesting in wall voids and behind appliances where you never see the ones doing the breeding.
2+
Pest types the typical home faces a year Most homes face more than one: mice in fall, ants in spring, spiders and roaches in between. Almost nobody gets away with buying just one product.
$399+
Average first exterminator visit Plus quarterly retreatment. Most contracts are 12-month minimum: $600–$1,200/year for chemical perimeter spraying along every surface your kids and pets touch.
How one device covers four pests

The ones inside leave.
New ones don't move in.

PestRx works at both ends. The pests already inside start leaving, and new ones find your home harder to settle into than the yard next door, so they never move in.

PestRx technology diagram showing ultrasonic waves from the plug-in device driving a mix of indoor pests (mouse, cockroach, spider, ants) away
Technology 01
Drives Existing Pests Out

The pests already inside pick up PestRx's ultrasonic field through the floors, walls, and baseboards they travel along. The space stops feeling safe to them. Over the first days, they begin clearing out. No bait. No spray. No bodies to clean up.

Technology 02
Prevents New Pests From Moving In

The same ultrasonic field also keeps new pests from moving in, and it works the same way on all four. Rodents, roaches, spiders, and ants all take the path of least resistance, so they go where it's easy. PestRx makes your home the harder choice, so it doesn't get picked as a place to nest or feed. It runs at 25,000–65,000 Hz, above anything your household can hear.

Technology 03
Why most plug-ins quit after a week

Here's the honest version. Pests adapt. Give them one steady tone and within a week or two they treat it like a refrigerator hum and stop reacting. That's why the $15 to $30 fixed-frequency devices quit. PestRx varies its pattern instead of holding one note, which helps it keep working longer. It stays above the hearing range of humans, dogs, and cats, so your household doesn't hear it.

01
Plug into any standard outlet

One per floor covers most homes. Nothing to assemble or set up.

02
It starts working on power-up

All three layers begin the moment you plug it in. You won't hear a thing.

03
Your home stops being worth the trouble

The pests inside head out, and new ones passing through pick somewhere easier instead of your home.

The questions buyers ask us most
How far does one unit reach?
One unit covers the room it's in. Sound does not pass through walls or closed doors, no matter what other brands claim (the FTC has acted on those whole-house coverage claims). Plan one device per room you want protected, and start where the activity is.
How long until the pests are gone?
Most homes notice activity easing over the first couple of weeks as pests clear out and stop coming back. Give it the full 30 days, and if you're not happy, ship it back for a refund.
Is it safe for my dog or cat?
Yes. PestRx runs above what dogs and cats can hear, with no chemicals, no residue, and nothing for kids or pets to touch. One exception: keep it out of any room with a hamster, gerbil, or fish, since small caged pets can be sensitive to the frequency.
What if it doesn't work for me?
Full refund within 30 days, no questions asked. Just reply to your order confirmation email and we'll take it from there.
$0.33/day
Already pest-free? Stay that way. Plug in PestRx before the first sighting. The 5-pack runs at $0.33/day, one unit per room, and ships free. One-time purchase.

How fast you see a change depends on the pest and how bad it is
Days 1–3
It starts on power-up
The field runs the moment you plug in. A light problem, or a single pest like a few ants or spiders, can ease within days. A heavy or well settled infestation, or several pests at once, takes the full window. Both are normal.
Days 3–7
You may see more, not less
It's common to spot a few more pests early as they get pushed out of hiding toward the exits. This is the part that makes people quit too soon.
Days 7–14
It quiets down
Most homes see activity drop off through the second week as pests clear out and new ones pass the house by.
Day 14+
It stays quiet
Leave it plugged in and it keeps working in the background, season after season. No refills, no resprays, nothing to clean up.

Not seeing a change by week three? Move a unit toward where the activity starts, or use the 30-day guarantee. No hard feelings, no hoops.

"reduced the spider and ant activity but didnt clear it completely. my 1920s farmhouse has more gap and crack access points than i realized going in. customer support was actually great, immediate on the refund, no hassle whatsoever. i think this works, just not as a standalone solution when youve got real structural issues like i do."

HelloPest response

Patricia is right, and we should have caught this earlier. PestRx repels. It cannot block a structural gap that gives pests direct entry. For older homes with foundation cracks or deteriorated weatherstripping, sealing entry points first is necessary. Patricia shipped the units back and we refunded her right away. If she ever seals those gaps, we'll make it right at no charge. Marcus, HelloPest

"bought ONE unit for a 2400 sq ft two story house to deal with mice. didnt work. contacted support and they explained i needed AT MINIMUM 3 units for that square footage, thats on the product page but i totally missed it. they sent me a 2-pack at no extra charge to complete coverage. after that it worked exactly as described. my mistake honestly"

HelloPest response

This one's on us. The coverage calculator is there to prevent exactly this situation, and we should do a better job surfacing it. Brian's right that one unit can't cover a full two-story home, ultrasonic frequencies don't pass through floors or walls. We made it right with a free 2-pack. Leaving this review up because undercovering is the #1 reason PestRx underperforms. HelloPest Support

Safe by design

Works on pests.
Not on your household.

The frequencies PestRx uses are inaudible to people, dogs, and cats, and they don't affect electronics, WiFi, or medical devices. (Fish and small caged pets are the one exception, noted below.)

Children

Ultrasonic frequencies are inaudible to humans of all ages. No chemicals, no residue, nothing for little hands to touch.

Dogs & Cats

Dogs and cats can't detect PestRx's operating frequency range. No chemicals, no residue, nothing for them to touch.

Fish & Small Pets

Fish, hamsters, gerbils, and other small caged pets may be sensitive to ultrasonic frequencies. Do not place PestRx in the same room as their habitat.

Electronics & WiFi

Runs on a completely different frequency from WiFi, Bluetooth, and baby monitors. Zero interference with your devices.

Target
↑ Human and pet hearing ends below 25 kHz

PestRx operates at 25–65 kHz, entirely above the hearing range of humans, dogs, and cats. Your household hears nothing. Rodents, roaches, spiders, and ants are sensitive to vibration and sound in this range. They pick it up through their legs, antennae, and (for rodents) hearing, and avoid the surfaces and rooms carrying it.

Questions & answers

The honest answers, including what PestRx won't do.

What pests does PestRx actually work on?

PestRx is built for the everyday indoor pests that share your floors and walls: mice and rats, cockroaches, spiders, and ants, with help against other crawling insects like fleas and stink bugs. Each one is sensitive to vibration and sound in this range, mice through hearing, insects through their legs and antennae.

I bought a cheap ultrasonic device before, and it stopped working after a week. Why is this different?

This is the most common objection we hear, and it's a completely fair one. Every $15–30 ultrasonic device on Amazon emits a fixed frequency. Pests are adaptive. Within a week they habituate to a constant signal and stop responding. It becomes background noise, like a refrigerator hum. PestRx uses an adaptive pattern sweep that varies its frequency pattern instead of holding one note, so it doesn't hand them a single fixed tone to tune out the way a $20 device does. We won't pretend pests can never adjust to anything, so give it 7 to 14 days and move a unit if a room isn't changing. But if you gave up on a plug-in repeller before, you gave up on fixed-frequency. Not on the technology itself.

How many units do I need for my home?

It depends on your home's layout. Square footage matters less than where the entry points and food zones sit relative to each other. A multi-story house with a garage and finished basement needs different coverage than a 1-bedroom apartment, and a townhouse with shared walls needs different coverage than either. Take the 2-minute coverage quiz for a count built around your specific home.

Will pests get used to it over time?

Cheap fixed-frequency devices, yes. That's their main failure mode: a single steady tone becomes background noise within a week or two and pests stop reacting. PestRx varies its pattern instead of holding one note, which helps it keep working longer. We won't claim pests can never adjust to anything. What we'll say honestly: give it the first 7 to 14 days, move a unit if one particular room isn't changing, and the 30-day guarantee is there if it doesn't work for you.

Will it interfere with my WiFi, pacemaker, or other devices?

No. PestRx works on sound, not radio. It emits high-frequency sound waves in the 25–65 kHz range, a completely different thing from the radio signals that WiFi, Bluetooth, and devices like pacemakers use. It plugs into a standard 120V outlet and runs passively. There's nothing for it to interfere with.

Do I need to keep it plugged in permanently?

Yes, for ongoing protection. Once the current pests clear out, new ones can move in, especially as the seasons turn. Keeping PestRx plugged in year-round creates a continuous barrier. No refills, no resprays, no maintenance. One device, plugged in, doing the job of the cabinet full of products you replaced.

Does it kill pests, or just repel them?

It deters. It doesn't kill. Pests go where life is easiest. PestRx makes your home the harder, less comfortable option, so they move on. The ones already inside feel the field and head back out to easier territory. New ones read your home as occupied before they ever settle in. Killing the one bug you can see doesn't fix anything when more keep coming. Making your whole home a place they avoid does. No dead pests to clean up. No bait residue near your kids or pets.

Will it clear an infestation that's already established in my walls?

Be honest with yourself here. If something is already nesting deep in your structure (a carpenter ant colony in damp framing, rats breeding in a wall cavity, rustling or scratching inside the walls), that's a job for a licensed pest professional to locate and treat at the source. PestRx is built to deter and prevent. It keeps new pests from moving in, and pushes out the ones passing through your living space. Once something has nested inside the framing, a plug-in is downstream of the real problem. We'd rather tell you that than take your money.

Can I use it outdoors or in my garage?

Yes for garages, unfinished basements, and attics with a standard 120V outlet, and that's often where the problem starts. Rodents and insects slip in through garage-door seals, crawl-space gaps, and utility penetrations before they reach your living space. Outdoors: PestRx is built for indoor use and isn't weather-rated for direct rain. Covered porches, screened enclosures, and weatherproof shed outlets work. For perimeter coverage, a unit on the nearest interior wall still works the adjacent exterior surface.

What if I have a severe infestation? A nest in the walls, pests by the dozens?

We'd rather give you an honest answer than oversell. PestRx works best as continuous, whole-home deterrence for light-to-moderate problems. For severe situations, a colony nesting in the framing, a heavy rodent infestation, or pests streaming in from one open entry point, PestRx alone isn't the full fix. In those cases, seal the entry point first, address any moisture or food source, then run PestRx as continuous prevention. Use the 30-day guarantee window to confirm it's working. If it doesn't, we'll refund you.

One device, the pests that travel your floors and walls

One plug-in for the pests that get into your home.

Most homes end up with a cabinet full of single-pest products: one for mice, one for roaches, one for spiders, one for ants, and another for whatever turns up next. PestRx runs an ultrasonic range that the pests which feel their way along your floors, walls, and baseboards tend to avoid, so one plug-in does the work of a whole shelf. One device. No extra purchase.

Mice & rats

Rodents hear ultrasonic sound natively, and the 25,000–65,000 Hz range sits in the band they find stressful, so they avoid the rooms where it's running.

Cockroaches

Sense substrate vibration through cercal receptors at the rear of their abdomen. The signal reads like predator activity, so they leave the cabinets and wall voids they hide in.

Spiders

They sense vibration through their legs, the same sense they use to hunt. It throws that off, so they stop setting up in your corners and move on.

Ants

Foragers pick up the signal and redirect to easier food outside, so new scouts never lay a trail into your kitchen to begin with.

Other pests

Fleas, stink bugs, and other crawling insects that feel their way along the same floors and baseboards tend to avoid the field too.

Same plug, same 30-day money-back guarantee. No second purchase to cover the rest of the house.

The last pest purchase

11,247 homes traded a cabinet of pest products
for one plug-in.

They stopped buying a new product for every pest and plugged in PestRx instead. No more reaching for a new spray, trap, or exterminator every few weeks. Plug it in, and you're done thinking about it.
